Abstrakt:	A new approach to the modeling of electromagnetic wave propagation and penetration in and around electrically small objects is presented. The traveling electromagnetic wave from a source is simulated by the finite-difference time-domain solution of Maxwell's equations, and a sub-gridding technique is imposed at points of interest in order to observe the electromagnetic field at high resolution. The computational burden caused by the requirement for a large number of time steps has been ameliorated by implementing the state-of-the-art quasi-static approach. The method is demonstrated by finding the induced electromagnetic fields near a buried pipeline that runs parallel to 400-kV power transmission lines; results are presented and discussed.
